I Ban'd" I 91 ofthe;woodenfiamemftherlower sash arexprovid'ed with flat surfacesfi 'andioutwardly' or rearwardiy" such surfaces" terminate in shal low" inwardly" or fbrwardiyj' facing grooves 28': About the inner-edges of" the mentioned rails of said wooden or outer frame of "the" lbwersas'h I 3 beads 29 are formed on tiiefbrWard'facesmftiie" rails:

The" corresponding rails" of" the inner metal frame oftlie-iow'er' sash are in" transverse section" somewhat in-the form ofogeeiteurves'and" each such metal frame part comprises a fiat major portion orbodY' 30; the forward edge of whicii is bent 'up on'= itse1f"t'o provide the concavo-eonvege or channeP shaped portioni 3I'- which", when the inner frame is in ciosed positiom disposed over and" embraces tiiebead 2'95 The outerzedge of eachzbody pjortio *3IF-i5'aa10 b'ent into as concavmeonvexe fermatib 18 and I9 of the outer or wooden frame of the lower sash.

These parts engage over a relatively wide area,

preferably they should be a careful fit. In addi- I tion, under the described conditions, that is, when the inner metal frame is in closed position in the outer wooden frame of the lower sash, the reversedly bent or transversely concave-convex portion 3| of the top and side rails of such metal frame embrace or are disposed about the beads 29 of the corresponding members of the wooden frame. Somewhat similarly the outer or convex portion of the channel-like portion 32 of the described rails of the inner metal sash are received in or partly received in the channels or grooves 28 of the complemental parts of the wooden frame of the lower sash.

It will be understood that the top and side rails of the inner metal frame may be in one piece bent into the inverted U-shaped required or they may comprise separate pieces connected at the corners in any suitable manner. The bottom rail 2| of the inner metal frame also includes a flat body portion 33 which, when the sash is closed, lies against the flat inner surface portion 34 of the bottom wooden rail I1 and, in addition, suchbottom metal frame member or rail includes an outer flange 35 which overlies a portion of thenouterside ofthe bottom rail I! and further includes av flange 36 to which the hinges 24 and are attached. With thi construction, it will be seen that thesaid inner glass or pane carrying metal frame of the lower sash may be swung from the closed position described to the open position described. This will be illustrated by a comparison of Figs. 6 and 7 of the drawings.

Extending inwardly from the flat portions and 33 .of the respective inner metal frame members are inwardly directed flanges 31, which flanges are all aligned and all are located slightly inwardlt of the reversedly bent portion or the transversely concave-convex channel-like portion 32 of the top and side rails of the inner frame. and a similar .portion 38 carried by the lower rail of such inner metal frame. Window light or pane of glass 26 is located within such inner metal framewith its edge portions against the outer side of the described flange 31. Then the space between the edge portions of said glass panev and the channel portions 32 and 38 are filled in with putty as at 39 completing the mounting of the glass in the inner ormetal frame of the lower sash [3 of the window.

The reception of the beads 29 by the concavoconvex channel-like portions 3| of the lower sash and the location of the channel-like portions 32 or at least portions thereof within the groove or channel 28, all when the hinged innerframe of.

metal frame in the closedpositiondescribedand such means is adapted for manual release and manual manipulation so that the lower inner frame may be released and swung to an open position wherein it extends inwardly with respect to the outer frame of the lower ash. This releasable securing or locking means involves recesses opening through the front rounded or beaded edges 29 of the side or vertical rails of the lower outer or wooden sash and also opening through the inner fiat surfaces 21 of the frame members of said sash. Such recesses in the drawings are designated 40.

Within'the lower portion of each such recess is a latch block generally designated 4| having a notch 42 opening through its upper end. These latch blocks are held in place as by screws 43 passing through openings 44 in the latch blocks and threaded into holes or openings 45 in the frame members It and IS. The latch blocks lie flush with the inner faces 21 of the framemembers and the upper ends of the latch blocks are spaced from the upper ends of the recesses4ll 22 and 23 is provided in its flat portion 30 with i a vertically extending slot 46 and when the inner or metal frame is in closed position, this slot 46 has its lower portion overlapping the notch 42 in the latch block 4i and has its upper portion disposed a considerable distance above theupper end of such latch .blocks but still within the length defined by the recess 40 in the adjacent frame member of the lower sash.

Extending through the slots 46 are latch bolts 41 each having an enlarged diameter inner end portion 48 adapted to be received in a notch 42 of a'latch block and each having its outer end passing through the vertical portion 49 of a finger piece 56 and headed over at the outer side of such vertical portion as at 5|. Finger pieces 50 in addition to the vertical portions 40 include horizontal portions 52 adaptedto be grasped as between the thumb and index finger for manipulation. 1

When the inner or metal frame is closed, the latch bolts 48 pass inwardly through the open inner edges of the recesses 40 and then are dropped down, moving in the slots 46 so that their enlarged diameter portions 48 enter the recesses 42 in the upper ends of a pair of latch blocks. Under these conditions, the inner or .metal frame is secured in closed position, which closed position has been described above. When it is desired to open the inner metal frame, the finger pieces 50 are raised as by grasping their horizontal portion 52 so as to carry the latch bolts upwardly out of the notches 42 and then the entire inner frame is swung forwardly on the hinges 24 and 25. Thus, it will be seen that the inner frame is easily latched closed and that the latch means is easily released and the inner frame swung open.

The inner frame may be swung open for the purpose of ventilation or so that the outer surface of its window light or pane of glass 26 will be convenient for cleaning without the necessity of the cleaner sitting outside on the window sill or even sliding upwardly the lower window sash.

' Further, the inner frame may be swung slightly J or even prohibits its being raised in its ways be--.

open to afford some ventilation even though there is rain. Also, swelling of the wooden outer frame of the lower sash, such as makes diflicult tween the strips II and 12, will not prevent the user from obtaining ventilation since the "metal:
